The biggest development of the week was not actually on the site itself, but on the Facebook pages that represent the Mirran and Phyrexian factions. Each faction got a recruitment video designed to lure you (yes, you!) to its side. Go to the Mirran Faction Page and the Phyrexian Faction Page to see them.
Now that that's out of the way, let's get down to it.
On the Mirran side, Farris of the Anvil continues his story in a new field report. There's concept art for goblin equipment and red creatures. And, of course, there are short flavoriffic snippets scattered throughout the site.
